 EUROMOD's microsimulation allows researchers and tax policy experts to simulate, evaluate and compare the impact of various tax policies and benefits on household incomes based on existing national tax codes in the EU.The model gives an estimation of how work incentives affect each country's population separately as well as the EU-zone population as a whole.As it is used to calculate the effects of already existing policies, it is used to evaluate tax-benefit policy reforms on poverty, inequality and individual government budgets.
